TIRE-TOOL.

TQ all whom it may concern.:

Be it known that I, Pnns'roN G. TAYroR, a citizen of the' United States, residing at Mumford, in the county of Robertson and State of Texas,'have invented new and useful Improvements in Tire-Tools, of which the following is a specilication.

This invention relates to tools employed' for expanding demountable tire-carryingv rims of the split type, and its object is to provide a tool of this kind by the use of which the rim can be easily contracted for removal from the tire and also with equal facility expanded to its proper position after the tire has been` putback on the rim.

The object stated is attained by means ci a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the saine may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing Figure l is plan view of the tool showing its application to the rim;

Fig. 2 is a side elevation thereof, and

Fig. 3 is an elevation showing the tool poi sitioned for expandingI the'rim.

Refei'rino specifically to the drawing, 5 denotes a lever of suitable length having pivotally connected adjacent to its outer end two links 6 and 7, respectively, connection being made by rivets 8 and 9, respectively, or any other suitable means. The link is connected to the lever outward of the connection of the link 7 with the latter.

The link (3 carries a hook 10 having a straight and fiat shank l1 whichis pivotally connected at its inner end, as shown at 12, to the link 6, a short distance back of its outer or free end. The link 6 is a lat'inetal bar havin a twist 13 .intermediate its ends to bring t e pivots 8 and 12 at a right angle to each other.

The linkl 7 carries two hooks 14 and 15, respectively, at the outer ends ofstraight Hat shanks 16 and 17 respectively, said shanks being both pivotally connected at their inner ends, as shown at 18, to the link 7, a short distance back of its outer or free end. This link is also a fiat metal bar having a right angled twistI 19 intermediate its ends to bring the pivots 9 and 18 at a right angle to each other.

Bpecincation of Letters Patent.

Application led August 16, 1918. Serial No. 250,166.,

The outer endo the link 6- is blunt as shown at 20, and the outer end of the link 7 has a sharpened transverse edge 21, and also a slight lateral curve or bend 22.

In use, to contract the rim shown at 23, the links 6 and 7 are swung to extend from opposite sides of the lever 5, and the Shanks 16 and 17 are spread to extend divergingly from opposite sides of the link 7. The hooks 14 and 15 are slipped over the rim edge andA the hook 10 is slipped over the rimedge at a diametrically opposite point. The two hooks 14 and 15 securely anchor the lever 5 to the rim 23 at two points, and upon swinging the lever in a direction to draw the hook 10 inward, the rim is contracted in an obvious manner. The rim may be held locked. in contracted position by means of a suitable latch device 24 carried by the lever 5 and adapted to be slipped over the link 6- after the lever is swung to draw the links inward whereby the lever is held against swinging back to release the links.

'lo expand the rim 23, the links 6 and 7 in conjunction with the lever 5, are used in the following manner:

The links 6 and 7 are set to extend from opposite sides of the lever 5 and the hooksV .which secures the two ends of the rim to?) 2gether at the'break. The sharp end 21 of the 'link 7 is placed against the inside of the rim on the side of the break opposite that side where the abutment-is located.. The lever 5 is now swung in the direction of the linkt/7 A until the ends ofA the rim at the break come together. The sharp end 210i the link 7 holds when pressure isput on the lever, and t the link 6 pushes against the abutment 25,

in view of which the hereinbefore described operation', by whiehthe rim is expanded, is readily eli'ected.

I claim:

1. A tire tool' comprising' a lever, a pair of links pivotall y connected to the lever adjacent to one end thereof, one back of the other, the extremities of the links having transverse rim-engaging edges and hooks having their shanks pivotally connected to 'une nlfs @mak of he oui-er enfle thereof, fi the lnks bask of the outer ens thereof, one 10 We hookf; being pefjpencicuof tho Shanks carrying o, pair of hooks f L ,f 1.5i axis of the links. adapted to 'ne splead to extond from oppofo Lm .1 Qompisng o. have?, @pair of site sides thereof, the pivotal axis of the ks ph* y oonneoed to th ever ad hooks being perpendicular to the pivotal meent om and thereof, one back of the axis of the links.

the exte tas of the links -mving In testimony whereof oix my signature.'
